The heterocyclic bases and ester halides used as starting materialare known and can be obtained by known methods.

Workingup of the reaction mixtures may be carried out in the usual way.

The excellent antimycotic effect of the newly prepared compounds is surprising and could not be foreseen, since after the elaborate investigations of T. Noguchi, Y. Hashimoto, K. Myazaki and A. Kayi, J. Pharm. Soc. Japan, 88 (2), 227-234 (1968), 88 (3), 335-343 (1968), 88 (3), 344-352 (1968) and 88(3), 353-358 (1968) ithas hitherto been assumed that only compounds of the type have anantimycotic effect and even these only if R denotes a methyl group.

The excellent antimycotic activity of the compounds of the present invention maybe shown by thefollowing inhibition values (minimum inhibition concentration i.e. MIC) in relation to a variety of fungi pathogenic to humans and animals. 2,3-dihydro-N-[naphthyl-(2)- oxy-thiocarbonyH-l,4-benzothiazine was selected as a compound representative of those of the present'invention and theMlCs of this compound against various fungi are listed below in Table 11.

A rapid retrogression of the primary symptoms of infection (reddening of the skin and loss of hair) takes place, and the animals can be considered completely cured on the 10th day after infection. A typical course of infection is illustrated in Table 2.

Table 2 be found in the Warburg test for the new compound (a) at concentrations of 0.2 to l y/ml substrate.

The compounds of the present invention are useful for'the treatment of fungal infections in both humans and animals. With regard to the veterinary medicine aspects, they have been found especially suitable for combating fungal infections caused by the following fungr:

Trichophyton verrucosum Trichophyton quinckeanum Trichophyton rubrum Trichophyton mentagrophytes Trichophyton gallinae as well as Microsporon species, particularly Microsporon canis and felineum.

In general, it has proved advantageous to administer topically formulations containing about 1% to about 2% of active ingredient once to twice daily, inorder to achieve effective results. Nevertheless it may be neces- Evaluation of course of infection after days Untreated 6 control:

In some cases it may be sufficient to use less than the aforesaid minimum amount whereas in other cases it will be necessary to go beyond the aforesaid upper limit. If larger amounts are administered, it may be advisable to distribute these over the day in several individual doses. The same range of dosage is envisage for application in human medicine, and the other explanations given above apply analogously.

The compounds of the present invention can be ap plied alone or in combination with pharmaceutically acceptable diluents or carriers. Suitable forms for application in combination with various inert carriers are powders, sprays, aqueous suspensions, elixirs, syrups and the like. Such carriers comprise solid extenders or fillers, a sterile aqueous medium as well as non-toxic organic solvents and the like. In the aforesaid case, the therapeutically active compound should be present at a concentration of about 0.5 to 90 per cent by weight of the total mixtures, that is to say in quantities which suffice to achieve the above range of dosage.

In the case of aqueous suspensions and/or elixirs, the active ingredient can be used together with diluents such as water, ethanol, propylene glycol, glycerol and similar compounds or combinations of this type.

The invention further provides a medicament in dosage unit form comprising at least one of the new active compounds either alone or in admixture with a solid or liquid diluent or carrier. The medicament may include a protective envelope containing the active compound and, if used, the diluent or carrier.

The term medicament in dosage unit form as used in the present specification means a medicament as defined above in the form of discrete portions each containing a unit dose, or amultiple or sub-multiple of a unit dose of the active compound or compounds. Such portions may, for example, be in monolithic coherent form, such as tablets, suppositories, pills or dragees; in wrapped or concealed form, such as wrapped powders, cachets, sachets, or capsules; in ampoules, either free or as a sterile solution suitable for parenteral injection; or in any other form known to the art. 1

The invention also provides a method of combating fungus infections in humans and animals (especially domestic animals) which comprises applying to the animals at least one of the new active compounds either alone or in admixture with a solid or liquid diluent or carrier.

The following non-limitative example more particularly illustrates the present invention.
